Step 4, optical signal is converted to electric signal by demodulation, is transferred in the Rank of storage system；
Step 5, storage system couples corresponding wavelength and is modulated when transmission response signal returns to processor core；
Step 6, optical signal is coupled to the optical-fiber network organized where present communications processor core (109) and transmitted by storage system,
Processor core (109) end is demodulated, converts optical signals to electric signal, finally sends processor core for response signal
(109)。
